Airtel — Unable to receive benefit of recharge of rs 699 on my prepaid number

I have recharged with 699 on my Airtel prepaid number and as it was mentioned in airtel app and on web one can avail the benefit of Amazon prime for 56 days with this recharge but i think that it was just to mislead the airtel users as the prime benefit that has been provided to me is of mobile edition which is nowhere mentioned in the description of the recharge but for other recharge of rs 3359 it has been mentioned that prime mobile edition will be provided once recharged. Kindly refer to the attached screenshot image for the clear picture.

I have written multiple mail to the nodal officer Airtel Delhi division and also talk with customer care multiple times but they are neither responding to my mail which i have sent them on 4th December 2022 nor the customer care is providing any resolution.
